The R720 supports up to 2 xeon CPUs and 8 drives in 2U. If configured appropriately it will work fine as a Hadoop node. For example, 2x Xeon, 64GB RAM, 8x 2TB SATA configured as JBOD, would be a reasonable worker node. Buy 20 of those and now you're cooking with gas. :) The C2100 is probably somewhat cheaper for a given storage amount since it fits 12 disks in a 2U chassis (so you don't need to buy as many machines to achieve a given amount of capacity). Dell doesn't provide a configurator for that model so I can't compare prices. Apparently it's using the previous generation of Xeon -- 5500/5600 versus e5 on the R720 -- which probably means poorer throughput per watt. The right answer will depend on your application and workload. -andy
